A group of parents has appealed a decision by a Louisville high school to allow transgender students to use the restrooms and locker rooms that correspond with their sexual identities.

The Atherton High School site-based decision-making council will meet next week to discuss the appeal, which was filed by Louisville attorney Clinton Elliott, who is with the Christian-based legal group Alliance Defending Freedom.

The council voted last month to amend its policy after school Principal Thomas Aberli decided to allow a transgender student to use the girls' restroom and locker room. The student was born male but identifies as female.

The appeal says the school panel's decision was "inconsistent with state and federal law, inconsistent with concerns for safety and inconsistent with concerns for liability."
